Title: Optical apparatus for measuring transmission factor and reflectance
Inventor: JIN MATSUO
IPC: G01N21/3563
Filed: 1986-06-19
Abstract: PURPOSE:To measure the transmission factor and reflectance of a sample by a simple operation, by providing a changeover mirror and switching it properly. CONSTITUTION:A luminous flux S comes into a sample 3 via flat mirrors 1 and 2 and the reflected light therefrom travels to a concave mirror 8 via flat mirrors 4 and 6 for measuring reflection, when a changeover mirror 7 is located at a non-operation position (b) outside an optical path. On the other hand, the transmission light through the sample 3 is reflected on the changeover mirror 7 switched over to the operation position (a) in the optical path via a flat mirror 5 for measuring transmission and travels to the concave mirror 8, following the same optical path as for the measurement of the reflection. The light reflected from the concave mirror 8 is turned to be incident light from a sample chamber section via a flat mirror 9. When the changeover mirror 7 is at the non-operation position (b), the reflected light from the sample 3 is emitted while the transmission light is emitted when it is at the operation position (a).

Filed: 1978-11-22
Abstract: PURPOSE:To omit the installation of the rectifier circuit to each group by securing the AND in the state of the pulse row and then applying the pulse row to the counter circuit after making sure that each row contains the pulse row. CONSTITUTION:The multi-frequency signal applied to input 1 is applied to isolation filters 3 and 4 via amplifier circuit 2 to be then isolated into the high and low group frequencies. These isolated frequencies are applied to limiter circuits 5 and 6 plus BPF7-14, and the maximum voltage appears to either output to be detected by detection circuits 15-22. The output of the detection circuit is applied to AND circuits 38-45 via OR circuits 30-37. On the other hand, the pulse rows are generated in proportional to the two signals applied at the output of OR circuits 23 and 24. This output is applied to AND circuit 27 to secure the AND to apply it to storage-type counter circuit 55. Circuit 55 counts the input pulse number up to the set value, and thus the output is applied to timer circuit 29. The output of circuit 29 is applied to one end of circuits 38-45 each to actuate the receiver.

IPC: G01N21/49
Filed: 1985-06-29
Abstract: PURPOSE:To confirm whether the operation of an ultrasonic wave generating mechanism is good or not by adding an independent circuit for adjusting the ultrasonic wave generating mechanism. CONSTITUTION:An independent circuit 18 is branched in parallel at a point between a differential amplifier 8 and a switch 9. When switches 17a and 17b are switched to lower sides, an oscillator exciting circuit 7 is driven continuously to continue to radiate an ultrasonic wave into a cell 1. Consequently, the state variance of a scattered light due to turbulence or bubbles of cavitation generated in the cell 1 appears as the output of the amplifier 8 and is displayed on a display device 15 through amplifiers 19 and 14. The oscillation frequency of the circuit 7 is adjusted while seeing the display on the display device 15 to find the maximum value of the display value, thereby facilitating the matching adjustment to match the resonance frequency of an ultrasonic wave radiator 2 consisting of an oscillator and a horn, to the oscillation frequency of the circuit 7 Thus, it is confirmed whether the operation of the ultrasonic wave generating mechanism which controls the capacity of an oil concentration analyzer is good or not while fulfilling the essential function which measures and displays the oil concentration of a sample water.
